How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones employ microphones to pick up ambient sounds and generate an anti-noise tone that blocks unwanted noises. They're ideal for headphones skullcandy blocking out rumbles and chatter from planes and trains but they won't make much difference to the sound of the squealing brakes or your friend's animated conversations.

Active noise cancellation requires great isolation, either through padding your ears with a solid seal with earbuds or over-ear headphones. We've also tested whether the headphones block out lower frequency noises like traffic or train noise.

What is noise cancellation?

Noise cancelling is a feature that helps listeners focus on their music or audiobook, without distraction from the background noise. Noise cancelling headphones come with microphones that block external sounds from getting to your ears. This allows you to listen to your music or audiobook in peace.

Active noise cancellation (ANC) is among the most popular headphone features on the market. It is available from a variety of different brands of headphones with a variety of colors and sizes, and even on some models that are budget-friendly. The technology behind them is simple: ear cups or earbuds contain tiny microphones that "listen" to ambient noise frequencies and then play back equal but opposite noise waves to eliminate them before they get to your ears.

This is referred to as destructive interfering. The crests and valleys of the waves cancel each and leave only the music you're listening to. This works great on monotonous, continuous sounds like the drone of an airplane engine, or that coworker Bob who can't seem to stop talking. However it's not as effective on louder or more frequent sounds that are more difficult to detect and eliminate like the ping of a keyboard or that alarm beeping from your smartphone.

Another kind of noise-isolation is passive, which reduces the sound by forming an ear-to-ear seal with the padding of the ear cups. This is a good choice for those who don't need to rely on batteries to provide ANC function, but require a peaceful working environment or at home.

It's important to remember that every pair of headphones requires some form of power, whether it's for audio processing or battery, for them to function. Although ANC can block out most external noise, it's important to remember that the headphones aren't able to create a solitary cone around your ears - if the ambient sounds are too loud they'll simply bleed through to your ears. It is important to wear your headphones tight enough so that there are no gaps in the fit. This will allow you to get the maximum benefit of ANC.

How does it work?

The technology behind noise cancellation headsets is based on tiny microphones inside earcups or buds which listen to sounds around you. They're processed inside the headphones to produce an opposing sound wave that effectively blocks out the sounds and blocks them from reaching your ears.

Sound waves, whether they're emanating from outside or your music, are made up of air molecules that oscillate. This means that sound waves have a height or amplitude. This is measured by the distance between peaks of an unsteady graph. Sound waves with higher intensities are larger, whereas those with smaller magnitudes are smaller. ANC headphones make use of this to create an audio that is in opposition of the sounds that you hear around you.

ANC headsets are equipped with several features to block out background noises, including feedback mics and ANC chipsets. These chips use algorithms that convert sound and then release a counter-signal which is similar to launching antiballistic missiles against the warheads coming towards them.

The ANC drivers in each ear cup produce these opposing signals. When you turn on the ANC by pressing a button on your headset, sounds from the environment are reduced or eliminated.

The technology behind ANC is impressive, it does come with a few trade-offs. The additional electronics required to enable this technology can add weight and bulk to your headphones. They also require more power, which could cause a decrease in the life of the battery and some high-frequency hiss.

One other issue is that a number of users have reported feelings of dizziness or disorientation while wearing ANC headphones. While this can be frustrating but it's usually due to something else that is triggering these feelings, not the ANC headphones themselves.

The good news is that more advanced ANC headsets are beginning to address these problems. The Bowers & Wilkins PX7, for instance, comes with different ANC modes such as 'office', 'plane' and 'city' with an adjustment slider that lets you customise the volume of external sound that you wish to hear. Apple's AirPods Pro 2 feature a similar feature, with a 'Ambient Aware mode' that digitally adjusts the level of ANC according to your surroundings.

What are the best headphones for noise cancellation?

Noise cancelling headphones can enhance your listening experience. They can help you focus in the office or block out engine noise on trains, planes and buses. These headphones with best noise cancelling are great to use for commutes or working from home. They are compatible with all audio equipment, including smartphones, tablets and computers.

Over-ear headphones are more comfortable than in-ear models. They have a larger band and cushioned cups that sit over your ears. This helps keep them in place for longer. They are also more effective in blocking out noise from the outside. There are exceptions, and the best headphones for noise cancellation will depend on your preferences in music and lifestyle.

Most over-ear headphones provide some degree of noise isolation, but the level of noise reduction will differ greatly based on the design and the way they fit your ears. An insufficient fit could let in ambient noise and even affect the quality of bass. A great tip is to change the headphones' stock tips to determine if they improve fit and reduce ambient noise, and you can do this with the majority of earbuds too.

In-ear headphones can be less comfortable for long listening sessions, since they sit in your ears, rather than over them. They can be more comfortable when you tilt them back or forwards to adjust their size. They are also lighter, making them more portable and easier to carry. In our tests, all earbuds offer some level of noise-isolation, but not as good as over-ear Headphones Skullcandy.

What should I look for in noise-cancelling headphones?

The most effective noise cancelling headphones reduce background noise to allow you to concentrate on your music and not be distracted by the surrounding. To achieve this, they usually make use of active noise cancellation (ANC) but not all ANC headsets are created equal. It's important that you consider the kind of ANC, whether it's over-ear or in ear, as well as their build quality.

Over-ear and in-ear headphones are the most popular choices and both provide excellent noise isolation. While in-ear headphones are more comfortable for extended durations, in-ear headphones provide greater portability and can be less bulky. Over-ear headphones tend to be more expensive but often offer a better sound quality, while in-ear models offer a more affordable option with a solid sound quality.

Certain ANC headphones have different levels of ANC offering you the possibility of adjusting the level of ANC to the situation that is at hand. You can choose to disable ANC on an airplane, on public transport, or at home, but switch it back on when at work or at home to stop the whirrr of your PC's cooling fans or the lawn mower of your neighbour. A lot of headphones have a 'transparency mode' that allows external noises to pass through, so you can hear important ambient sound like traffic or conversations.
